Make use of the fact that we split upon acquiring mutexes anyway and refine points-to-sets for mutexes. This means getting rid of spurious warnings about releasing mutexes that are not held.

Closes #1287.

CHANGES:

* Remove unmaintained analyses: spec, file (goblint/analyzer#1281).
* Add linear two-variable equalities analysis (goblint/analyzer#1297, goblint/analyzer#1412, goblint/analyzer#1466).
* Add callstring, loopfree callstring and context gas analyses (goblint/analyzer#1038, goblint/analyzer#1340, goblint/analyzer#1379, goblint/analyzer#1427, goblint/analyzer#1439).
* Add non-relational thread-modular value analyses with thread IDs (goblint/analyzer#1366, goblint/analyzer#1398, goblint/analyzer#1399).
* Add NULL byte array domain (goblint/analyzer#1076).
* Fix spurious overflow warnings from internal evaluations (goblint/analyzer#1406, goblint/analyzer#1411, goblint/analyzer#1511).
* Refactor non-definite mutex handling to fix unsoundness (goblint/analyzer#1430, goblint/analyzer#1500, goblint/analyzer#1503, goblint/analyzer#1409).
* Fix non-relational thread-modular value analysis unsoundness with ambiguous points-to sets (goblint/analyzer#1457, goblint/analyzer#1458).
* Fix mutex type analysis unsoundness and enable it by default (goblint/analyzer#1414, goblint/analyzer#1416, goblint/analyzer#1510).
* Add points-to set refinement on mutex path splitting (goblint/analyzer#1287, goblint/analyzer#1343, goblint/analyzer#1374, goblint/analyzer#1396, goblint/analyzer#1407).
* Improve narrowing operators (goblint/analyzer#1502, goblint/analyzer#1540, goblint/analyzer#1543).
* Extract automatic configuration tuning for soundness (goblint/analyzer#1369).
* Fix many locations in witnesses (goblint/analyzer#1355, goblint/analyzer#1372, goblint/analyzer#1400, goblint/analyzer#1403).
* Improve output readability (goblint/analyzer#1294, goblint/analyzer#1312, goblint/analyzer#1405, goblint/analyzer#1497).
* Refactor logging (goblint/analyzer#1117).
* Modernize all library function specifications (goblint/analyzer#1029, goblint/analyzer#688, goblint/analyzer#1174, goblint/analyzer#1289, goblint/analyzer#1447, goblint/analyzer#1487).
* Remove OCaml 4.10, 4.11, 4.12 and 4.13 support (goblint/analyzer#1448).
